Answer 1

Given:

The frequency of a transition is 3.13.1 \times× 10^{10}10 10 HzHz.

To find:

What is the energy of this transition? [h = 6.6266.626 \times× 10^{-34}

Solution:

From given, we have,

The frequency of a transition = v = 3.13 × 10^{10} Hz

The constant factor = h = 6.6266 × 10^{-34}

we use the formula,

E = hv

where, E = energy of the transition

v = frequency of the transition.

So, we have,

E = [6.6266 × 10^{-34}] × [3.13 × 10^{10}]

⇒ E = 20.74 × 10^{-24}

∴ The energy of this transition is 2.0 × 10^{-23} J
